Lemon Blondies Ingredients

Pantry staples form the base of these lemon blondie brownies. Adding fresh lemon zest and juice infuses vibrant aromas and enhances the flavor. 

The sweet lemon glaze, made with powdered sugar, zest, and juice, adds a glossy sweetness and takes these bars over the top.

Substitutions and Additions

SALTED BUTTER: Unsalted butter can be used, but make sure to add a pinch of salt to maintain the desired flavor balance.

GRANULATED SUGAR: Brown sugar can be substituted for a hint of caramel undertones in your lemon blondie bars.

LEMON ZEST & JUICE: Experiment with other citrus fruits like oranges or limes for unique variations on this easy recipe.

GLAZE: You can customize the glaze by adding a splash of vanilla extract or a touch of your favorite citrus liqueur.

How To Make This Lemon Blondies Recipe

Here’s a step-by-step guide to creating these easy lemon blondies:

STEP ONE: Preheat the oven to 350°F. Line an 8×8 baking pan with either parchment paper or heavy-duty aluminum foil. Spray the parchment paper or aluminum foil with nonstick cooking spray.

Be sure to leave a slight overhang with the parchment paper or aluminum foil to help lift the lemon blondies out of the pan. This will make it easier to cut them.

STEP TWO: Add the flour, baking powder, and salt to a small mixing bowl (2-3 cups). Whisk to combine.

STEP THREE: Beat the softened butter for 30 seconds to 1 minute until smooth. You can do this either in the bowl of a stand mixer, or in a medium-sized mixing bowl (2-3 quarts) with a handheld mixer, on medium-high speed. 

STEP FOUR: Add the granulated sugar and continue to mix for another 1-1½ minutes or until light and fluffy.

STEP FIVE: Lower the mixer speed to medium-low. Add the room-temperature eggs, one at a time, beating well after each egg.

STEP SIX: Keep the mixer speed on medium-low. Add the flour mixture to the wet ingredients and beat just until combined.

STEP SEVEN: Add the lemon zest and drizzle in the lemon juice. Mix just until incorporated.

Add more or less lemon juice or zest as you desire to adjust the depth of lemon flavor in the blondies and the glaze.

STEP EIGHT: Evenly spoon the batter into the prepared pan. Gently tap the baking dish on the counter to release any air bubbles. 

Bake for 18-20 minutes, or until a toothpick inserted comes away with a few crumbs. The blondies will not be golden brown; they will be a light yellow.

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to check your blondies at the lower end of the recommended baking time.

Remove the baking dish from the oven and allow the lemon blondies to cool for about 30 minutes or until cooled. Once the blondies are cooled, make the lemon glaze.

STEP NINE: Add the powdered sugar to a small bowl (2-3 cups). Whisk in the lemon zest and fresh lemon juice until smooth. 

STEP TEN: Use either a silicone spatula or an offset spatula to evenly smooth the glaze over the lemon blondies. Allow the glaze to “set” before using the parchment or foil overhang to remove the lemon blondies from the baking dish. 

If your kitchen is on the warm side, you can chill the lemon blondies in the refrigerator before slicing.

STEP ELEVEN: Use a sharp kitchen knife to cut four slices x four slices before serving.

How To Serve

These delicious lemon blondies are incredibly scrumptious, making them a charming addition to any dining experience:

Enjoy them on their own as a quick snack to satisfy your sweet cravings with a touch of zesty delight.

Serve them as a dessert, perhaps warm with a scoop of vanilla ice cream on the side and a dollop of whipped cream.

Pair them with your favorite tea or latte, allowing the citrus notes to complement the beverage’s flavors.
